1、About one million Americans are diagnosed annually with skin cancer.【單選題】

A.every year

B.severely

C.actively

D.every month

正確答案:A

答案解析:題干大意：每年大約有100萬美國人被診斷為皮膚癌。畫線詞annually：每年。選項(xiàng)中，every year：每年。severely：嚴(yán)重的。如：The report says the drugs had meaningful results only in the most severely depressed patients. 這個(gè)報(bào)告指出藥物只是對于最嚴(yán)重的抑郁癥患者有顯著效果。actively：積極地。如：Just as a rider's weight shifts can help sustain the equilibrium of a wobbly bicycle, actively balancing the lift forces on each wingtip is key to aircraft roll control. 騎自行車的人移動(dòng)重心有助于穩(wěn)定搖晃的自行車，就飛機(jī)而言也一樣，要控制轉(zhuǎn)動(dòng)動(dòng)作，關(guān)鍵就在于主動(dòng)平衡左右翼尖的升力。

2、Animal's "Sixth Sense"
A tsunami was triggered by an earthquake in the Indian Ocean in December, 2004. It killed tens of thousands of people in Asia and East Africa, Wild animals, however, seem to have escaped that terrible tsunami. This phenomenon adds weight to notions that they possess a "sixth sense" for disasters, experts said.
Sri Lankan Wildlife officials have said the giant waves that killed over 24,000 people along the Indian Ocean island's coast clearly missed wild beasts, with no dead animals found.
"No elephants are dead, not even a dead rabbit. I think animals can sense disaster. They have a sixth sense. They know when things are happening" H. D. Ratnayake, deputy director of Sri Lanka's Wildlife Department, said about one month after the tsunami attack. The waves washed floodwaters up to 2 miles inland at Yala National Park in the ravaged southeast, Sri Lanka's biggest wildlife reserve and home to hundreds of wild elephants and several leopards.
"There has been a lot of ______ evidence about dogs barking or birds migrating before volcanic eruptions or earthquakes. But it has not been proven," said Matthew van Lierop, an animal behavior assistant at Johannesburg Zoo. "There have been no specialist studies because you can't really test it in a lab or field setting," he told Reuters. Other authorities concurred with this assessmetn.
"Wildlife seem to be able to pick up certain phenmenon, especially birds. There are many reports of birds detecting impending disasters," said Clive Walker, who has written several books on African wildlife.
Animals certainly rely on the known senses such as smell or hearing to avoid danger such as predators. The notion of an animal "sixth sense" -or some other mythical power-is an enduring one which the evidence on Sri Lanka's ravaged coast is likely to add to. The Romans saw owls as omens of impending disaster and many ancient cultures viewed elephants as sacred animals endowed with special powers or attributes.
【單選題】

A.experimental

B.apparent

C.scientific

D.chemical

正確答案:B

答案解析:下一句說，這些跡象并沒有被證實(shí)。因此，這些跡象不可能是scientific的，而experimental和chemical的詞義與上下文不配合，因此也不是答案。只有apparent（明顯的）與上下文的意思相配。

3、Better Control of TB Seen if a Faster Cure is Found
The World Health Organization estimates that about one-third of all people are infected with bacteria that cause tuberculosis. Most times, the infection remains inactive. But each year about eight million people develop active cases of TB, usually in their lungs. Two million people die of it. The disease has increased with the spread of AIDS and drug-resistant forms of tuberculosis.
Current treatments take at least six months. Patients have to take a combination of several antibiotic drugs daily. But many people stop ______ they feel better. Doing that can lead to an infection that resists treatment. Public health experts agree that a faster-acting cure for tuberculosis would be more effective. Now a study estimates just how effective it might be. A professor of international health at Harvard University led the study. Joshua Salomon says a shorter treatment program would likely mean not just more patients cured. It would also mean fewer infectious patients who can pass on their infection to others.
The researchers developed a mathematical model to examine the effects of a two-month treatment plan. They tested the model with current TB conditions in Southeast Asia. The scientists found that a two-month treatment could prevent about twenty percent of new cases. And it might prevent about twenty-five percent of TB deaths. The model shows that these reductions would take place between two thousand twelve and two thousand thirty. That is, if a faster cure is developed and in wide use by two thousand twelve.
The World Health Organization developed the DOTS program in nineteen ninety. DOTS is Directly Observed Treatment, Short-course. Health workers watch tuberculosis patients take their daily pills to make sure they continue treatment.
Earlier this year, an international partnership of organizations announced a plan to expand the DOTS program. The ten-year plan also aims to finance research into new TB drugs. The four most common drugs used now are more than forty years old. The Global Alliance for TB Drug Development says its long-term goal is a treatment that could work in as few as ten doses.
【單選題】

A.as if

B.as though

C.as far as

D.as soon as

正確答案:D

答案解析:答題時(shí)請注意句首的But這個(gè)詞，與上句意思發(fā)生轉(zhuǎn)折。4個(gè)選項(xiàng)中as if、as though都是“仿佛，宛如”的意思，as far as則是“至于……，就……而言”的意思，填在這里均不合適，只有as soon as（一……就……）才恰當(dāng)。

4、Many economists have given in to the fatal lure of mathematics. 【單選題】

A.error

C.attraction

D.miracle

正確答案:C

5、Light Night, Dark Stars
Thousands of people around the globe step outside to gaze at their night sky. On a clear night, with no clouds, moonlight, or artificial lights to block the view, people can see more than 14,000 stars in the sky, says Dennis Ward, an astronomer(天文學(xué)家) with the University Corporation for Atmospheric Research( UCAR) in Boulder, Colo. But when people are surrounded by city lights, he says, they're lucky to see 150 stars.
If you've ever driven toward a big city at night and seen its glow from a great distance, you've witnessed light pollution. It occurs when light from streetlights, office buildings, signs, and other sources streams into space and illuminates (照亮) the night sky. This haze (朦朧) of light makes many stars invisible to people on Earth. Even at night, big cities like New York glow from light pollution, making stargazing difficult.
Dust and particles of pollution factories and industries worsen the effects of light pollution. "If one city has a lot more light pollution than another," Ward says, "that city will suffer the effects of light pollution on a much greater scale."
Hazy skies also make it far more difficult for astronomers to do their jobs.
Cities are getting larger. Suburbs are growing in once dark, rural areas. Light from all this new development is increasingly obscuring (使變模糊) the faint (微弱的) light give off by distant stars. And if scientists can't locate these objects, they can't learn more about them.
Light pollution doesn't only affect star visibility. It can harm wild life too. It's clear that artificial light can attract animals, making them go off course. There's increasing evidence, for example, that migrating (遷徙) birds use sunsets and sunrises to help find their way, says Sydney Gauthreaux Jr. , a scientist at Clemson University in South Carolina, "When light occurs at night," he says, "it has a very disruptive (破壞性的) influence." Sometimes birds fly into lighted towers, high - rises, and cables from radio and television towers. Experts estimate that millions of birds die this way every year.
How does light pollution affect wildlife? ______【單選題】

A.Animals may go off course.

B.It helps migrating birds find their homes.

C.Animals are afraid to go out after sunset.

D.It helps birds fall asleep.

正確答案:A

答案解析:本題難度不大，答案依據(jù)比較明顯，在文章第六段第三句，這句話談到，人造光源會(huì)誤導(dǎo)動(dòng)物，造成動(dòng)物偏離飛行路線，回來看選項(xiàng)，A項(xiàng)符合原文句意，是答案。
